Deciding what to buy for your machine tool parts, coolants, and supplies usually comes down to a fork: is the gap in the fluid itself, in the mist-delivery hardware, or in the electronics that move the machine? These four products cross all three layers. The biggest mistake is treating a coolant sprayer and a driver board as similar purchases. Pick the layer you're missing first, then look at the choices below.
Quick take
- Need cutting fluid for CNC machining, sawing, drilling, milling, or grinding? Premium Synthetic Machining Coolant is the direct fluid option.
- Need a simple mist-delivery unit? Mist Coolant Lubrication Spray System Unit combines cooling, lubrication, and chip blowing in one compact assembly.
- Need a broader mist setup? Coolant Cooling Spray Pump Mist Sprayer System gives you two sprayers, a solenoid valve, and a filter.
- Building a CNC controller setup? CNC Kit With TB6600 4 Axis Standard Version Driver Board & HB Motor/PSU bundles a four-axis driver board, four Nema14 motors, and a 12V 10A power supply.

Product notes
Premium Synthetic Machining Coolant - 128 FL. OZ. (1 Gallon) for CNC Cutting
This is the product to pick when the missing piece is the fluid. The 128-ounce gallon is the only straight coolant option in the group, and it is aimed squarely at CNC machining and grinding work. It covers multi-metal machining, sawing, cutting, drilling, milling, and grinding, with corrosion protection, stability, and foam control. It comes in pail packaging and uses a simple mixing ratio: 18 ounces of coolant to a gallon of water. The practical limit is that it is only the fluid side of the system; delivery happens separately.
Coolant Cooling Spray Pump Mist Sprayer System for CNC Lathe Milling Machine New
This is a delivery package rather than a fluid container. It arrives as a custom bundle with two sprayers, a solenoid valve, and a filter, plus one tank, so you can build a mist-cooling loop with more than a single nozzle. The system needs your own air compressor with air pressure between 2KG and 8kg, so plan for that connection. The compact design and long-service-life feature make it a fuller kit than a simple single-nozzle unit, but it is not something you can use until you attach it to a compressor and a coolant supply.
Mist Coolant Lubrication Spray System Unit for CNC Lathe & Milling Machine
If you want to try mist cooling on a CNC lathe or milling machine without a large spend, this unit is the entry point. It combines cooling, lubricating, and blowing metal chips in a single spray unit, with adjustable airflow and spray volume. The package includes a blue tube of about 30cm and a transparent tube of roughly 1.5m, so you have the basic line set out of the box. It is the lowest listed price in this comparison and the most direct way to add mist delivery. The trade-off is that this is one compact unit, not the two-sprayer bundle with a solenoid valve and filter.
CNC Kit With TB6600 4 Axis Standard Version Driver Board & HB Motor/PSU
This kit is the right pick when your project is motion control, not coolant. It bundles a 4-axis TB6600 standard driver board, four Nema14 21oz-in stepper motors, and a 12V 10A switching power supply. The board supports 2- or 4-phase Nema8 through Nema34 stepper motors and works with software such as Mach3, Lincxcnc, and KCam4. The DC 12V 10A power supply is included, and the model name identifies it as a four-axis standard Nema14 kit. If you were shopping for mist coolant or cutting fluid, this is the wrong layer of the setup-it is electronics for moving the machine.
Final recommendation by use case
Choose the Premium Synthetic Machining Coolant if your shop already has a delivery method and you need cutting fluid for multi-metal machining and grinding. Choose the Mist Coolant Lubrication Spray System Unit if you want a simple one-unit way to add mist delivery to a CNC lathe or mill. Choose the Coolant Cooling Spray Pump Mist Sprayer System if you need two sprayers plus a solenoid valve and filter in one delivery purchase. Choose the CNC Kit With TB6600 4 Axis Standard Version Driver Board & HB Motor/PSU if your build needs a four-axis driver board, motors, and a 12V power supply. Match the layer you're missing, and the decision narrows quickly.
